Notes on w11 systems: w11a for and S3BOARD
Basics
The sys_w11a_s3 system is a w11a implementation for the Digilent S3BOARD board. For complete configuration, see sys_conf.vhd. The most important features are:
| Property | Value |
|---|---|
| CPU options | FPP: no; Cache: 8 kB |
| Memory | 1024 kB from SRAM via s3_sram_memctl |
| Devices | DL11:2; DZ11, PC11, LP11, DEUNA, RK11, RL11, RHRP, TM11, IIST, KW11P, M9312: yes |
| Diagnostics | rbmon: yes; ibmon: yes; dmpcnt: yes; dmhbpt: 2; dmcmon: yes |
| Rlink | 460 kbps via USB-RS232 cable connected to the RS232 port |
Usage
The board has 8 LEDs and offers only a compactified console light emulation. The memory size of 1024 kB allows starting all oskits.
For complete instructions on how to run operating system images, see w11a_os_guide. The default setup is:
SWI = 00101010
ti_w11 -tu<dn>,460k,break,xon @<oskit-name>_boot.tcl
Status & History
The S3BOARD was the first w11 development platform. All inital w11 developments were done with this board. In 2011, the developemt switched to the Nexys 2 board, as this board offered full 4 MB memory, and more importantly, a high speed rlink connection. The S3BOARD is still available, but is no longer actively used. The design is retained for historical and nostalgic reasons.
